Hot Wheels' Twitter-enabled vending machine coughs up free Camaro diecasts

There are still plenty of companies that haven't gotten the whole social media thing down pat yet, but Hot Wheels isn't one of them. During the recent Canadian International Auto Show in Toronto, Hot Wheels created a lot of buzz for itself by using a vending machine filled with Chevrolet Camaro models, but instead of money to get the cars, show attendees just had to use Twitter.
To get the free car, people were asked to send a tweet to Hot Wheels Canada saying what they liked about the new Hot Wheels Edition Camaro, and including the #ChevyCIAS hashtag. This seemed to be a popular marketing tool, too, as AdWeek reports that the @HotWheelsCanada account more than tripled in followers during the course of the 10-day show. Looking ahead, this could open up even more innovative marketing possibilities using social media.
Check out the video posted below to watch how it works, and while the auto show has ended and the free-car giveaway has too, we're almost certain that some of the 1,500 freebies will make their way onto eBay.

Motor Trend puts Chevy Camaro Z28 and Porsche 911 GT3 Head 2 Head

Motor Trend admits, "This is an unfair comparison." But that doesn't make it any less fun to watch when they pit a Camaro Z/28 against the Porsche 911 GT3. The former has a 7.0-liter V8 with 505 horsepower and 481 pound-feet of torque shifted through a six-speed manual. The latter has a 3.8-liter flat-six with 475 hp and 324 lb-ft shifted through a seven-speed dual-clutch transmission. Yet those are only the little disparities – the big disparities are mass and money: the Camaro weighs 3,882 pounds and costs $76,150 as-tested, the Porsche weighs 3,267 pounds and costs $145,785. But they're both about hardcore performance, so MT takes them out on the street, to the drag strip, to the parking lot for figure eights and a skidpad test, and finally to Big Willow for Randy Pobst to give his professional assessment. Remember when a lotta people spent a lotta time debating Pirates vs. Ninjas? This is like that, only it's the "haul-ass good-time car" vs. the "track surgeon." Enjoy the debate in the video.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
